Pivotally connectedy to ythe forwardly through. the openings 5. formed in the plate 1:,.said arms being bent upwardly at their forward ends` as shown at 15r to. receivethe buttons 16- having designating marks thereon.. A.

VThe shaft 13. also,l carries the swinging frames 1T, 18, 1.9, 20, 2l.,V 22;. 23', and 241, the

trames. being elongated in shape shownv and of such a size that, one will` be received 85 shaft 13 are thekey arms 1.4LV which extend within the confines of the others asis, more clearlyillustrated" in Figs. l and 3 of the drawings... These, swinging ,frames normally extend downwardly at.- an angley as more clearly illustrated in lilig.,y loff the. drawings,

being held or supported in this position by means of the plates 25 and 26 which are secured to the bottom plate 6 intermediate the ends 1 and 2. The upper edges of these plates 25 and 26 are each inclined downwardly, towards the forward edge, as shown at 27 to allow the frames to be swung in a manner which will be later described. Secured to each of the plates 25 and 26, Vadjacent the upper edges thereof, are the reinforcing strips 28 and 29, the strips 28 extending from the front of the plates and the reinforcing strips 29 being ositioned adjacent the4 rear edges thereof.V

becured to the plate 26 and to the end 1 is a guide bar 30, more clearly illustrated in Fig. 2 of the drawings, which is provided with the upwardly extending projections 31 between which the ends of vthe frames will operate and be guided. Secured to the forward edge of each 4of the frames by means of the screws 32 or the like is a plate 33 which has upwardly: extending projections 34 to be engaged by the key arms 14. The arrangement of these plates relatively to the frames is more clearly illustrated in Figs. 4, 5 and 6 of the drawings and it is thought that a description of one will suiiice for all. Any number of projections may be formed on the plate and they may be of differentwidths as shown. It will be understood that when some of the key arms are operated that only one frame will be swung Whereas when other key arms are operated or depressed a plurality of frames willbe swung. Where the frame is to Ybe swung by a single key the projection 34 will be relatively narrow but when a plurality of the key armsoperate the same frame the projections will be relatively wide-so as to be engaged by a plurality of the key arms. The plates are removable and interchangeable so that different plates may be positioned upon different of the frames and by doing this various combinations may be obtained for discharging coins upon the operation of the different key arms. The arrangement of the projections on the plates relatively to the key arms is more particularly illustrated in Fig. 3 of the drawings and a more detail description of the operation will be later described.

Pivotally connected to the shaft 13 are the arms 35 which may be termed pusher arms, these arms being of the shape more particularly illustrated in Fig. 1 of the drawings and provided on one edge, intermediate the upper and lower ends, with a lug or projection 36 having the vertically'spaced eyes 37 and 38. As shown in Fig. 2 there are eight of these arms and one arm is connected to each of the frames 17, 18, 19, 20, 21, 22, 23 and 24 by means of a bracket 39 so that each frame as it swings will operate oneof the arms. Pivotally connected at 40 adjacent the upper end of each of the arms 35 is a finger 41 which extends substantially at right angles to the arm and has at the rear end a downwardly extending projection 42 provided with the eye 43. A coiled spring 44 has one end connected through the eye 43 and the opposite end connected through the eye 38 formed in the lug or projection A36 of the arm 35. A coiled spring 45 has one end connected through the eye 37 formed in the lug or projection 36 and the opposite end is connected to the angle iron bar 3. rlhe coiled spring 45 tends to draw` the upper end of the arm 35 rearwardly and thereby hold the frame in the position disclosed in Fig. 1 of the drawings. The pusher fingers 41 extend through longitudinally spaced openings 46 'formed in a plate 47 which. is connected to the ends 1 and 2. The coiled springs 44 normally hold the forward ends of these lingers in raised position in contact with the upper edges of the openings 46 in position to engage the lowermost coins carried in the compartments 48 of a coin tray 49 of usual construction. As the specific form of coin tray forms no part of the present invention it is thought that a detailed description thereof is not necessary other than to say that it has eight compartments for supporting the coins and is held upon the substantially horizontal portion 50 of the vertically extending plate 51 which is supported intermediate the ends 1 and 2 of the machine. The horizontal portion 50 has the upwardly extending projections 52 which extend through openings formed in the bottom of the coin tray and the plate 47 carries the pivoted catches 53 which engage projections formed on the back of the tray for holding the same against displacement. The vertically extending plate 51 has lugs 54 formed on each end to receive screws 55 or other suitable fasteners for connecting the plate to the ends'l and 2. Y

Aplate 56 extends parallel with the plate 51 but spaced therefrom. This plate 56 has the lugs 57 formed on each end to receive the screws 58 or other suitable fasteners whereby the plate is connected to the ends 1 and 2. A brace 59 is secured between the plates 51 and 56 by means of the screws 60 or other suitable fasteners, this brace acting as a support for the chute 61 which is positioned between the plates 51 and 56 as more clearly illustrated in Figs. 1 and 2 of the drawings. The chute is inclined so that its lower end passes through an opening 62 formed in the end 2, the upper end of the chute having a horizontal portion 63 which rests Vupon the upper edge of the end 1. The chute 61 is so positioned as to receive the coins discharged from the coin tray and deliver them through the opening 62 in the end;of the machine.

The plate 56 is provided along its lower edge with a plurality of longitudinally spaced hooks 64 to each of which is connected one end of a coiled spring 65 the opposite ends numana of the coiled springs being connected through eyesV 66 formed in the key arms 14.r These springs normally holding the key arms in raised position.

A bar 67 extends longitudinally of the frame and is supported by the ends 1 and 2. This bar has the notches 68 formed along its lower edge to receive the upper edges of the key arms 14 as more clearly illustrated in Fig.' 1 of the drawings. These notches act as guides for the key arms and prevent lateral movement of said arms.

The machinewill be supported upon the rubber feet 69 secured to the base late 6.

In the case of the key arm 14, earing the designating numeral l, adjacent the left hand end of the machine, said arm is provided with a downwardly extending projection 7 0 which will engage the upper surface of theend of the frame 22, it being noted that this particu.- lar key arm is so positioned that it would be impossible to engage a projection carried by any other frame.

Having fully described the details of construction I will now endeavor to set forth more in detail the operation. As the keys are depressed they will swing the frames so as to in turn swing the arms 35 and direct the pusher lingers 41 forwardly of the coin tray and discharge the coins which are in the path of' the lingers into the discharge chute 61, down which they passout through the opening 62 in the end 2. As has been previously stated the coin tray has a plurality of compartments in which are supported coins of different denominations and the designating marks on the keys show the amount of change to be delivered from the coin tray. Preferably there will be stacks arranged in the following manner. The first three stacks from the left hand end of the machine will be pennies,

ythe next stack will be nickels, the next two stacks dimes, the next stack quarters, and the last stack to the right of the machine fifty cent pieces. If one cent change is to be delivered either one of the keys bearing the designating mark 1 will be `depressed and through means of the kprojections either on the frame or on the left hand key .will depress the frame 22 and this will swing the arms 35 nearest the left hand end of the machine and discharge one penny from the stack of coins. The coin will be pushed from the stack by the pusher finger 41 and delivered into the chute 61. Iftwo pennies are to be delivered the key bearing the designating mark 2 willbe depressed and this will swing the frame 23 and the arm 35 which is connected thereto vto dis charge two pennies from the second stack adjacent the left hand side of the machine. As the particular form of mechanism for ejecting the particular number `of coins forms no part of the present invention a detail description thereof or detail illustrationisnot thought necessary. If three pennies are to be iramesa22 and 24therehy delivering onepennyf from; the: stack nearest. the left` handzendf, `of the machine and two .pennies fromthe third stack from: the left. hand senda. This; operation Willa-continue toy deliver the desired amount. of change andi thedepressionl of. the various; keys will:v swing those `frameshaving projec tions im the lineV ofA that particular keyl armv and discharge the necessary coins from their respectivestacks. I wish to call particular attention to.` the. fact, that the key arms, the; frames, and; theA pusher arms, are alli supported from a single shaft and that/.the frames have the removable andf interchangeable platesfconnected .thereto so; thatfbyv using plates having a different number. of projectionsor d-i-Eenent widthproj ectionsa different.

combination of; coins may bedelivered upon-v.

the'numeral 5, two keysfbearing the numeral 25., and two Ykeys bearing the numeral 50.L

The keys bearing the numerals 1, 2, 3 and 4 at the left of the machine are adapted for operation with the left hand of the operatorwhereloo as those keys bearing the numerals 1, 2,3 and 4 at the right of the machine are adapted for operation with the right hand; The key bearing the numeral 5 at the left of the machine when operated will eject'a single 5c piece, whereas when the key bearing the numeral 5 adjacent the middle of the machine is operated it will eject five pennies. Whenthe key 25at the left of the machine is operated a single 25e piece will be operated whereas when the key bearing the numeral 25 at the right of the machine is operated it will eject a 5 piece and two 10 pieces. When the key bearing the numeral 50 adjacent the midle ofthe machine is operated a single 5095 piece will be ejected whereas when the key bearing the numeral 50 at the right is operated a 25e piece, a 5 piece, and two 10 pieces will be ejected.

From the above it will be seen that the parts may be assembled in very compact form, so

that the machine may be moved quite easily from place to place, and that the operating Lno imo

able selector mechanism interposed between the operating keys and coin ejector arms whereby the ejector arms will be operated upon movement of the keys, and coins ejected from the desired stacks. Y

2. A change making machine comprising a receptacle for containing a plurality "of stacks of coins of diii'erent denominations, coin ejectorl arms, operating keys, swinging frames interposed between the keys and ejector arms, and interchangeable selector means carried by the frames, said selector means being adapted to be engaged by theoperating keys for operating the ejector arms for ejecting the coins. Y

`3. A change maker including a coin receptacle for supporting stacks of coins of dierent denominations, coin ejector arms, operating keys, and swinging frames interposed between the keys and ejector arms and connected to the arms, a plate detachably connected to each of the frames and having a plurality of projections Aextending upward` ly therefrom, the projections being formed and adapted to be engaged b-y one or more of the keys to swing the fra-mes to discharge the desired coin or combination of coins from the stacks by means of the ejector arms.

In testimony whereof I hereunto affix my signature. e
